David, Industrial Communications Engineers (I.C.E.) makes a couple of open
wire arrestors that I think are well designed.  On both legs of the open
wire they feature a DC short to ground (inductor) on the antenna side that
helps drain static ( and resulting noise) from the antenna, a gas tube to
ground for fast rise-time impulses, a high-voltage capacitor in series
between antenna and Xceiver, and a high resistance to ground on the input. 
In my opinion this is about as good as you can get short of disconnecting
and grounding the antenna well away from the shack.

quote author="David Wilburn"
A very interesting read, I have a couple of questions about practical 
considerations.


I have not found a way to safety ground ladder line and run it into 
the house.  After taking a lightning strike last year, I have no wish 
to have ladder line and / or balun's inside the house.

*Is there a way to properly ground that ladder line, and then run it 
into the house?
*If there is a practical way, I assume one uses a plastic box or no 
box at all?
